I found a wonderful quote from Roald Dahl today where he describes working in his writing studio. In this quote, he restates the description of my own experience in my shop from the post "Why?" much more eloquently than I ever could.
“You become a different person, you are no longer an ordinary fellow who walks around and looks after his children and eats meals and does silly things, you go into a completely different world. I personally draw all the curtains in the room, so that I don’t see out the window and put on a little light which shines on my board. Everything else in your life disappears and you look at your bit of paper and get completely lost in what you’re doing. You do become another person for a moment. Time disappears completely. You may start at nine in the morning and the next time you look at your watch, when you’re getting hungry, it can be lunchtime. And you’ve absolutely no idea that three or fours hours have gone by.”
